Demand side management for combined economic emission dispatch of dynamic distribution systems

Power distribution costs are no longer just a utility’s responsibility. Instead, in order to fulfil the soaring demand for power, the utilities place a strong emphasis on reducing the amount of harmful chemicals that are released into the environment. In this study, the distribution system comprising of 6 units is subjected to dynamic economic emission dispatch (DEED) both with and without demand side control (DSM). Every hour, the elastic loads are ideally scheduled by DSM and moved to times when the price of power is lowest. This serves to lower the system’s peak demand, lower the cost of its generation, and raise its load factor. For both of the microgrid test systems, DEED is carried out using the price-penalty factor (PPF) technique. As the optimization technique for the investigation, a recently developed JAYA algorithm is employed. Numerical results show the impact of DSM is lowering the peak demand, improving generation cost and reducing the generation costs of the system. Proposed JAYA outperformed other algorithms in consistently providing a reduced value of fitness function.
